OPENING MACHINERY FOR TEXILE FIBERS.

Application filed August 31, 182'?. Serial No. 216,768.

This invention relates to opening machinery for textile fibers and isparticularly applicable for the opening,v of hard cotton Waste.

Opening machines for hard cotton Waste are usually constructed With alattice feed apron, tivo pairs of feed rollers to ensure a firm hold ofthe Waste, a cylinder or drum with spikes thereon, a pair of cages, anda lattice delivery apron.

ln such machines the hard Waste is fed by the feed rollers to therapidly rotating spiked cylinder and is opened Whilst being held by thesaid rollers, after Which it is carried to the delivery cages.

Such machines have, however, the disadvantage that a certain proportionof the hard Waste being treated passes through the machine unopened andthe present invention is designed to overcome this disadvantage.

According to the present invention a plus rality of pairs of feedrollers are arranged at intervals around the periphery of the spikedcylinder, each successive pair being set closer to the spiked cylinderthan the preceding pair, and the Waste, after being treated at the firstpair, is carried to the second pair and, after being` acted on by thespiked cylinder Whilst being' held by the second pair, is carried to athird pair, being finally carried from the final pair to the deliverycages.

The invention is illustrated in the accompanyingdrawing Which'is avertical section through an opening machine having three successivepairs of rollers for presenting the fibers to the spiked cylinder.

The machine is constructed with a feed lattice A, feed rollers B Whichreceive the fibers from the lattice A, a cylinder C having its peripherycovered With spikes or ,Qarnett Wire clothing and rotating at arelatively hipgh speed and'to which the fibers are presented by the feedrollers B, a pair of perforated delivery cages D, and a delivery latticeE, all of which are of usual or known construction The spiked cylinder Cis surrounded by an air tight casing F in communication with a fan G, bythe suction of Which the fibers, after being' operated on by the spikedcylinder C, are removed from the feed rollers B. A guide plate H isarranged in the casing,` F above the feed rollers B to direct the fibersto a perforated rotating'drum J to the interior of which an air duct g,under the influence of the fan Gr, is connected, so that the bers aredeposited and held by suction on the 'periphery of the drum J. Asemicylindrical mask j is arranged in the interior ofthe drum J so that,as the drum rotates and the fibers are carried round to this maskedportion, the suction through the duct g will cease to act on them andthey Will .be delivered to the second pair of feed rollers B1Which areof smaller diameter than the preceding,v pair B. y Y

This second pair of rollers B1 again presente the fibers to the spikedcylinder C so that a further openingvof the fibers takes place.

A second guide plate H1 is arranged in the easing: F above the spikedcylinder@ to direct the fibers to a second perforated rotating drum J1,to the interior of which anair duct g1, under the infiuence of the fanG, is connected, sothat the fibers are disposed and held by suction onthe periphery of. the drum J1. l l

A semi-cylindrical mask f/'1 is arranged in the interior ofthe drum J1so that as the drum rotates and thefibers are carried round to themasked portion, the suction of the fan G Will cease to act on them andthey will be delivered to a third pair of feed rollers B2 which are ofsmaller diameter than the preceding' pair B1. This third pair of rollersB2 again presents the fibers to the spiked cylinder C so that a furtheropening of the fibers takes place.

The fibers are thenk carried by suction in` Y the usual Way to t-hedelivery cages D which deliver them to the delivery lattice E.

What I claim as my invention and desire to protect by Letters Patent isr- An opening); machine for textile fibers cornprising a casiniy havingan inlet opening at one end and an outlet opening at its opposite end, adrum rotatable in said casing and having spikes projecting from itsperiphery,

means in said inlet opcning'to receive teX-.

tile fibers and deliver same to said drum, a plurality of perforatedcylindrical cages in said casing' spaced around the periphery of saiddrum and rotatable in the same direction as said drum with theirperipheries in close proximity to the outer ends of the spikes of saiddrum, means for creating suction in said cages, a plurality of pairs offeed rollers,

each of said pairs of rollers being mounted xed mask mounted thereinopposite the pair adjacent the periphery of one of Said cages oifeedrollers associated therewith for shutand in close proximity to the outerends of ting off suction through the perforatons of 10 the spikes ofseid drum and adapted to resu'eh eege opposite such feed rollers.

eeive fibers directly from their associated In testimony whereof I havehereunto set cage and deliver same directly to the spikes my hand.

of said drum, each of said cages having a JAMES JOLLY.
